ABSTRACT

Background: The Maternal and Child Survival Program of United States Agency for International Development conducted a study in 2017 to assess the outcome of an initiative to strengthen Expanded Programme on Immunization (EPI) pre-service training. The pre-service training initiative was undertaken by the Ministry of Health (MOH) with support from partners in 2012-2016. The overall objective of the study was to assess the adoption and effectiveness of the initiative in the competency (knowledge, skills and attitude) of graduate nurses. Methods: The study included a conveniently selected sample of 14 pre-service training institutions, 23 field practicum sites, and 29 health facilities in western Kenya, and used quantitative and qualitative methods of data collection. Results: All pre-service training institutions were found to have adapted the WHO EPI prototype curriculum. Overall, tutors followed training method in the classroom as suggested in the curriculum, except evaluation of students’ learning lacked tests or quizzes. Students had opportunities for hands-on practical experience in the field practicum sites. Graduate nurses were found to have acquired the skills for vaccinating children. However, some pre-service training institutions lacked functional skills labs for practical learning of students. In addition, students did not receive up-to-date information on EPI program, and lacked knowledge and skills on monitoring and documentation of EPI coverage during preservice training. Conclusions: It appears that the EPI pre-service training strengthening initiatives facilitated competency-based EPI training of nurses in Kenya. However, preservice training institutions still have scope for improvement in the skills lab, hand-washing practice, providing up-to-date information, and training students on coverage monitoring and documentation.

1. Introduction

As of 2015, Kenya had 148 health training institutions, of which 102 are for nursing training, distributed in 36 of 47 counties [1] . The World Health Organization (WHO) recommended in its 2013 guidelines that health professionals training institutions should consider designing and implementing continuous training development programs for faculty and teaching staff that are relevant to the evolving healthcare needs of their countries [2] . However, recent advancements in health care science and technologies were not always incorporated into the pre-service training curricula [3] . In 2011, the WHO Africa Regional Office developed the Expanded Program on Immunization (EPI) prototype pre-service training curriculum (updated in 2015) for competency-based training in nursing and midwifery schools [4] .

From 2012-2016, the Kenya Ministry of Health (MOH), in collaboration with the Nursing Council and with the support of EPI partners, launched an initiative to strengthen EPI pre-service training for nurses. The initiative included adaptation of the WHO prototype curriculum and mid-level manager training for nurse tutors from all pre-service training institutions (public, private, and faith-based) across the country. The initiative provided tutors with the WHO EPI prototype curriculum and updated immunization manuals, and advocated to increase the quality and duration of field practicum from 2 weeks to 8 weeks. The Maternal and Child Survival Program (MCSP), the United States Agency for International Development’s (USAID) flagship global program that supported the initiative, conducted a study in March-April 2017 to measure the outcome of the initiative in terms of the development of competency (knowledge, skills, and attitudes) among the nursing students. The study was guided by the following research questions:

· To what extent has, the pre-service training institutions improved the immunization teaching and training tools.

· Are graduate nurses competent in providing immunization services once posted to health facilities after completing their pre-service education?

· What are the perceptions of graduate nurses of the EPI training they received during their pre-service education?

· What opinion facility managers and sub-county EPI supervisors have of new graduate nurses competency (knowledge, skills, and attitudes) on immunization?

2. Methods and Materials

2.1. Study Design

The study was a mixed-methods cross-sectional assessment. The design enabled the team to examine the outcomes of the interventions by collecting and triangulating qualitative and quantitative data from the training institutions, practicum sites, and health facilities where graduate nurses were posted; the perception of graduate nurse on pre-service training; and the perception of facility managers and sub-county supervisors on the competency of graduate nurses (Figure 1).

2.2. Selection of Study Sites

The study was conducted in western Kenya where MCSP carried out its project activities. The sites included in the study were pre-service training institutions, field practicum sites, and health facilities where graduate nurses were posted in Kisumu, Migori, Kakamega, Kisii, Homa Bay, Bomet, Bungoma, Transzoia, Elgeyo Marakwet, and Uasin Gishu counties. The sites for the study were conveniently selected based on whether training institutions were teaching EPI topics during the study period; students were available at the field practicum sites; and data collectors could reach and observe immunization sessions in the health facilities during the data collection period. The selected health facilities were included if a nurse was posted there in 2016 after graduating from pre-service education.

The total study sample included 14 training institutions including faith-based, for-profit, and public (Kenya Medical Training College or KMTC) training institutions, 23 field practicum sites, and 29 health facilities (Table 1).

2.3. Study Population

The study population comprised 14 nurse tutors at pre-service training institutions, 28 graduate nurses at health facilities, 21 health facility managers, and 16 sub-county EPI supervisors (Table 2).

Table 2. Number of tutors, graduate nurses, facility manager, and Sub-county EPI supervisors participated in the study, by county.

2.4. Sample Selection and Inclusion/Exclusion Criteria

Nurse Tutors: Tutors were included in the study for observation in the classroom if they received EPI training between 2012 and 2016, and excluded if they had not received EPI training.

Graduate nurses: Nurses were included in the study if they graduated from the selected pre-service training institutions in 2016, and excluded if they had received any EPI in-service training.

Facility managers: Managers were included were included in the study if they were officers’ in-charge at the health facility where graduate nurses were posted. All facility managers were available for in-depth interview and no one was excluded.

Sub-county EPI supervisors: Supervisors were included if they were the EPI focal person at the sub-county level, responsible for supervising EPI work in the selected health facilities. All Sub-county EPI supervisors were available for in-depth interview and no one was excluded.

The MCSP data collectors visited all selected pre-service training institutions, field practicum sites, and health facilities; and interviewed all nursing graduates, facility managers, and sub-county supervisors who met the criteria.

2.5. Ethical Review and Confidentiality of Participants

The research plan was determined to be exempted from human subject oversight by the John Snow Inc. (JSI) Institutional Review Board (IRB) in the United States and the IRB of Maseno University in Kenya.

The MCSP data collectors obtained consent from all study participants before administering the questionnaires. Participants’ names were not collected, and the information they provided was kept confidential during data collection, storage, and analysis.

2.6. Data Collection Tools

MCSP developed data collection questionnaires, pre-tested them at pre-service training institutions and health facilities that were not included in the study, and made minor changes in the tools based on the pre-test.

2.7. Data Analysis

MCSP entered quantitative data and analyzed using Microsoft Excel and generated simple frequency tables; and transcribed qualitative data into an electronic database and analyzed based on emergent themes.

3. Results

3.1. Improvement of Teaching and Training Tools in the Participating Pre-Service Training Institutions

The degree to which the participating training institutions improved the pre-service training was evaluated by reviewing adaptation of EPI Prototype curriculum, skills lab, availability of reference manual, competency of tutors, and skills practice of students’ in the field practicum sites.

1) Adaptation of WHO EPI prototype curriculum

Almost all pre-service training institutions found to have adapted the WHO EPI prototype curriculum either all or some priority topics recommended in the WHO EPI prototype curriculum. Five of the seven public (KMTC) training institutions adapted all EPI topics in their nursing curriculums. One adapted only the priority EPI topics; and the data collector was not able to review the curriculum of the remaining KMTC site, as the person responsible at the institution was not available during the data collection period. Faith-based and private institutions also varied in their degree of adaptation (Table 3).

2) Skills lab in the pre-service training institutions

Six of the seven KMTCs (but none of the faith-based or private training institutions) had a dedicated room used as a skills lab for the students; one institution did not set up a skills lab due to lack of space. KMTC skills labs had limited functional equipment; for example, only one KMTC had a functioning (though old) EPI refrigerator, two had nonfunctioning EPI refrigerators, and three did not have any refrigerators (functioning or non-functioning) in their skills labs. However, all six KMTC skills labs had a vaccine carrier, safety box, and auto-disable syringes. None of the faith-based or private pre-service training institutions had set up skills lab for the students (Table 3).

3) Availability of reference manuals

Three of the seven KMTCs (but none of the faith-based or private institutions) had a copy of the WHO EPI prototype curriculum available as a tutors’ reference manual at the time of the data collectors’ visit. None of the pre-service education institutions had a copy of the EPI manual available as a students’ reference manual. Probing revealed that tutors received a hard copy of the WHO EPI prototype curriculum and EPI manual (and a flash drive containing both) when they attended the mid-level managers’ trainings. However, the tutors did not print out more copies of the materials and when they were transferred away from the institutions; they did not leave the hard copy of the reference manuals at the institution.

4) Competency of tutors in the classroom

Twelve of the 14 tutors (86%) observed in the classroom were found to explain the learning objectives for the topic to the students. Nearly all tutors (93%) used the suggested training methods, covered the full contents for the curriculum topics. However, due to lack of skills labs and/or functional equipment in the labs, students did not receive proper demonstration of immunization materials. Only nine of the 14 tutors (64%) evaluated students’ learning using exercises or quizzes in the classroom (Table 4).

Table 3. Improvement in teaching and training tools in the participating pre-service training institutions, by ownership of the institutions.

Table 4. Competency of nurse tutors observed in the classroom of the pre-service training institutions.

5) Skills practice of students at the field practicum sites

Overall, all 23 field practicum sites had the prerequisites for providing students with basic skills in immunization, but there were several notable gaps. Twenty-one of the 23 field practicum sites (91%) had such fundamental prerequisites as accommodation for the students, a qualified maternal and child health (MCH) nurse or clinical officer to guide students, immunization services, EPI cold chain equipment and commodities, and a sufficient number of clients for students to observe and practice vaccination. However, the field practicum sites of private training institutions did not have EPI standard refrigerators, but refrigerators for home use; therefore, students of these institutions did not get the appropriate practical experience on cold chain and vaccine management. In addition, two private sites were deemed unsuitable as field practicum sites because they did not have an EPI-trained staff member available to guide the students. Students at all sites had opportunity for hands-on experience in EPI cold chain and vaccine management (placing, arranging, and removing vaccines in the refrigerator; packing and unpacking the vaccine carrier; and recording the refrigerator temperature). Students in all but one practicum site were observed providing health education to mothers/caregivers. The majority (96%) of field practicum sites were visited by tutors to oversee the students’ progress and practices. However, students were not universally trained in some important related skills, such as tracking defaulters and monitoring coverage (Table 5).

3.2. Competency of Graduate Nurses in Providing Immunization Services

1) Attitudes towards caregivers

All 29 graduate nurses demonstrated a positive attitude towards caregivers (greeting them, building rapport, and treating them with respect) as observed during the immunization session.

2) Infection prevention practice

A little more than half (52%) of the graduate nurses washed their hands with soap and water or used hand sanitizer before starting the immunization sessions. The other nurses did not wash their hands because their facilities lacked running water and soap or hand sanitizer. The majority of nurses followed the non-touch technique during vaccination and discarded used syringes and needles in a safety box immediately, without recapping (Table 6).

Table 5. Observation findings at the field practicum sites.

Table 6. Observation findings at the immunization session conducted by the graduate nurses in the health facilities.

*N = 19 nurses had client for BCG and Measles vaccination in the immunization sessions observed.

3) Immunization practices

Table 6 also shows that though the graduate nurses used good immunization practices overall, there were gaps in certain practices. More than three-fourths (79%) of graduate nurses conditioned the ice packs for the vaccine carriers, a recommended practice of packing vaccines. The majority of graduates performed correctly in terms of following the proper vaccination procedures, telling caregivers when to return for the next vaccine, and registering vaccines administered. However, fewer than half (41%) of the graduate nurses checked the vaccine vial monitor and expiry dates of the vaccines before administering them and explained the possible side effects of vaccination and their remedies to the mothers/caregivers.

4) Immunization knowledge

Table 7 shows that nurses’ broader knowledge about vaccination was mixed. Most (90%) knew how to identify the defaulters in the permanent register and could define a missed opportunity for vaccination. Two-thirds could interpret the stages of the vaccine vial monitor. Over half correctly listed contraindications for immunization. However, the nurses did not have the most up-to-date knowledge of the national EPI: for example, only 11 of the 29 (38%) knew about the tOPV to bOPV switch and less than one-quarter could to calculate the coverage rate and dropout rate.

5) Impression of the pre-service EPI training (graduate nurses)

Most graduate nurses said that they did not get most up-to-date information during pre-service training on new vaccines (e.g., rotavirus vaccine, inactivated polio vaccine, or measles second dose) and new cold chain technology (e.g., fridge tags for cold chain temperature monitoring) that have been introduced in the national EPI program.

3.3. Impression of Graduate Nurses’ Competency (Managers)

1) Facility managers

Two-thirds (67%) of facility managers felt that the graduate nurses had adequate

Table 7. Immunization knowledge of graduate nurses.

EPI knowledge and skills to vaccinate children. Managers agreed with graduates that the pre-service training did not provide up-to-date information, including new vaccines, contraindications, and fridge tags. They added that graduate nurses frequently lacked the knowledge and skills needed to prepare monthly summary reports and calculate coverage and dropout rates. However, more than half (52%) of the managers said that graduate nurses were capable of performing EPI activities even without in-service training. Almost all the managers believed that graduate nurses were respectful to caregivers.

2) Sub-county EPI supervisors

Most sub-county supervisors had the impression that graduate nurses acquired basic vaccination skills during their pre-service training, but lacked knowledge on new vaccines, cold chain maintenance, target estimation, coverage and dropout rate calculations, and how to prepare coverage monitoring charts. Seven of 17 sub-county EPI supervisors (41%) thought that the graduates would be capable of conducting immunization session when posted in the health facilities. Almost all supervisors believed that graduates nurses were respectful to mothers/caregivers.

4. Discussion

Health professional trainings must be designed as a competency-based medical education (CBME), not just as means to obtain certification [5] . Thus, students must acquire knowledge, skills, and attitude to apply in the clinical settings [6] . CBME requires an enabling environment and well-prepared teachers [7] [8] . Over the last decade, the EPI has undergone many changes, introducing new vaccines and technologies in the program and developing new strategies and guidelines to achieve high, equitable immunization coverage [9] .

1) Training quality

The MCSP study found that most tutors had good knowledge of the EPI related contents and followed the training methods suggested in the WHO EPI prototype curriculum. However, there was gaps in the learning labs for demonstration of EPI materials to students. None of the faith-based and private pre-service training institutions had skills lab for students. Though most public pre-service training institutions had a skills lab, they did not have functional cold chain equipment. These gaps had consequences: MCSP found that one-third of graduate nurses lacked knowledge on vaccine vial monitors, the marker for vaccine quality. In addition, there were gaps in tutors’ performance, more than two-third were not using exercise or quizzes to evaluate students’ learning progress.

It also appeared that the pre-service training did not provide students with up-to-date information on the new vaccines and cold chain technologies introduced in the national program. Almost two-third of the graduate nurses did not know about the tOPV to bOPV switch (switching from trivalent bivalent oral polio vaccine) that took place in the same year of their graduation. Most pre-service training institutions did not have a copy of the MOH’s updated EPI reference manual for nursing students. As a result, about half of graduate nurses did not have knowledge on all vaccination contraindications. Tutors received a copy of the reference manual along with WHO EPI prototype curriculum during the training, but they did not leave the materials in the pre-service training institution when they were transferred.

2) Skills practice for students

For optimal learning, students should receive experiential learning while observing, handling health care materials, using equipment, and practicing service delivery in the clinical placement sites [10] . Field practicum sites should be conducive for learning—adequate space, immunization services for observation and practice, appropriate equipment and commodities, trained personnel to serve as local guide and supervisor, and periodic supervision visits from tutors from the training institutes [11] [12] . Certain factors have been shown to be critical for learning, such as a proper clinical environment, cooperation from staff, and large number of clients at the clinical placement sites [13] [14] [15] .

The absence of skills labs and/or equipment in some participating pre-service training institutions was mitigated to some extent by the well-organized field practicum sites. MCSP found that the public health practicum sites were well-equipped and the environment was conducive for learning by students. Most practicum sites had immunization services, an EPI cold chain system with equipment and commodities, a client volume sufficient to allow students to observe and get hand-on experience in the vaccination session, and a qualified MCH nurse or clinical officer was there to guide students. This contributed to the competency among most graduate nurses observed in the vaccination session.

However, the field practicum sites in private pre-service training institutions had several deficiencies, including trained on-site local guides or mentors, EPI standard refrigerators, and low client volume, which limited opportunities for students. Some graduate nurses particularly graduated from private pre-service training institutions complained that they had to compete with each other to practice vaccination in the field practicum sites. In addition, in most field practicum sites student did not get hands-on experience in immunization coverage monitoring and documentation. This training deficiency was reflected in the graduate nurses’ skills. For example, fewer than of one-quarter of graduate nurse had knowledge on estimation of target population, calculation of coverage and dropout rate, and only one in 10 graduate nurses had knowledge on how to prepare a coverage monitoring chart. Observations from both facility and sub-county-level supervisors suggested that the new graduate nurses were able to vaccinate children but were deficient in on monitoring and documentation of immunization coverage.

3) Vaccination practices among nurse graduates

Vaccine safety, injection safety, and infection prevention and control are important aspects of immunization services and thus are included in the immunization training [16] [17] . The MCSP study found that graduate nurses had good vaccine and injection safety practices in terms of not reusing syringes, following the non-touch technique when giving injectable vaccines, and discarding used syringes and needles in a safety box immediately without recapping. However, a major deficiency was observed in hand-washing practices: almost half of graduate nurses did not wash hand before conducting vaccinations. There was no running water and soap (or hand sanitizer) available in certain health facilities, so it was not certain whether this was a gap in the nurses’ practices, a health system problem, or both.

Limitations of the Study

MCSP purposively selected the pre-service institutions, field practicum sites, and health facilities for this study. Therefore, findings are not generalizable to all pre-service training institutions in Kenya. Data collectors spent sufficient time at data collection sites to enable sufficient time for observations. However, the presence of the data collectors may have introduced observation bias—participants may have changed their behavior while under observation. The study’s use of multiple viewpoints (tutors, graduates, and managers/supervisors) served to limit any potential bias by allowing the researchers to triangulate the quality and outcome of EPI pre-service training.

5. Conclusion

Considering findings from the reviews and observations at the pre-service training institutions, field practicum sites, health facilities and impression of graduate nurses, facility managers, and sub-county EPI supervisors, we can conclude that EPI pre-service training improved in Kenya and that the graduate nurses acquired vaccination competency during pre-service training, though, more gaps existed in private training institutions. The improvement in EPI pre-service training can be attributed to the pre-service educational strengthening initiatives taken by MOH with partner support. Private pre-service training institutions should set up skills labs, and functional EPI equipment and materials should be made available for all public, private and faith-based training institutions. Updated EPI manuals should be given for nursing students in all pre-service training institutions. National EPI office should share information regularly with the pre-service training institutions, particularly when changes in policies and strategies occur, or when new vaccines and technologies added into the program. We recommend continuous knowledge update of nurses through on-line training and for enhancement of their skills; supervisors should conduct on-the-job training and demonstrate skills during monthly meetings. We also recommend for continuing medical education for teachers/tutors of the pre-service training institutions. Finally, we believe that the MOH and pre-service training institutions of other countries may find these study findings beneficial when planning to strengthen their own pre-service immunization training.
